Actually, they mean that the Earth is getting warmer more quickly than it has at any time past. That is an indisputable fact.
Most scientists think that greenhouse gasses are the cause. There is a wealth of observation to back up that hypothesis, but it is not proven beyond a doubt.
Most scientists are telling us that a warming Earth will change local climates in unpredictable ways, hence the term "global climate change."
None of that is based on "emotion drenched feelings of death of humanity", but on scientific research. There are some people saying that global climate change will be a disaster for the human race. That is an opinion, not based necessarily on scientific research. It could turn out to be correct, however.
What is not proven, is not based on research, and is almost certain to turn out to be wrong is the constant ranting on the radio saying that global climate change is a myth perpetrated by "liberals." All that kind of nonsense is doing is creating an audience for rant radio, and bringing in advertising dollars.
In a way, they are correct that the so called "debate" about global climate change is fueled by the desire to make money from the phenomenon.
